Arizona Sheriff Joe Arpaio, under federal investigation, has just released the “findings” of his six-month long “five-page investigation” into President Barack Obama‘s birth certificate, announcing he “suspects forgery.” Arpaio, who is not a certified documents specialist, just released a statement that questions President Barack Obama’s “eligibility to be president.” President Obama released his long-form birth certificate to the public on April 27, 2011.

Maricopa County Sheriff Joe Arpaio in a press conference today told reporters, “A six month long investigation conducted by my cold case posse has lead me to believe there is probable cause to believe that President Barack Obama’s long- form birth certificate released by the White House on April 27, 2011, is a computer- generated forgery. I do not believe that it is a scan of an original 1961 paper document, as represented by the White House when the long-form birth certificate was made public.”

This is the principle preliminary finding of a six-month on-going Sheriff’s Cold Case Posse law enforcement investigation into the authenticity of Obama’s birth certificate and his eligibility to be president.

Investigators advised Sheriff Arpaio that the forgers committed two crimes: first, in creating a fraudulent document which the White House characterized, knowingly or unknowingly, as an officially produced governmental birth record; and second, in fraudulently presenting that document to the residents of Maricopa County and to the American public at large as “proof positive” of President Obama’s authentic 1961 Hawaii long-form birth certificate.

Arpaio and his lead investigator Mike Zullo posted five videos, explaining their investigation. You can find them at the site of the Western Center for Journalism, but essentially the argument they’re making is that the date stamp and the registrar’s stamp on Obama’s long-form birth certificate were imported from somewhere else. Their proof for that claim? They said the stamps were on different layers on the document and could be moved freely when opened in editing software.

For the record, we opened the file using Adobe Photoshop and found that it contained only a single layer of information.

Zullo makes a similar argument about Obama’s selective registration card. This time, he insinuates that the year 1980 in the postmark has been tampered with. He says that since there were no 1980 stamps available currently someone cut a 2008 to show 08 and then flipped it to say 80.

(We wondered, being that the White House is so powerful, if they couldn’t just order a custom-made 1980 stamp.)

“[His] card isn’t just forged; it’s poorly forged,” he said.

Arpaio said he had not decided what to do next. One reporter asked if he would turn it over the Postal Inspector, who could look into the “forged” postmark stamp. Arpaio said it was a tough decision and he hadn’t made up his mind.

Arpaio, who calls himself “America’s Toughest Sheriff,” has been under investigation by a federal grand jury since 2009. He has been accused of or criticized for, among other issues:

Election law violation
Misuse of funds
Abuse of power
Racial Profiling
Lack of Cooperation with Department of Justice
Unconstitutional jail conditions
Arpaio also has been widely criticized by the United States Department of Justice, United States District Courts, Amnesty International, the American Civil Liberties Union (ACLU), the Arizona Ecumenical Council, and the American Jewish Committee.
